摘要:

在线规划器选择是为给定规划问题从预定义集合中选择求解器的任务。由于规划在计算上是困难的,求解器在规划问题上的性能差异很大。因此,预测它们在给定问题上的性能的能力非常重要。尽管已经采用了多种学习方法,但对于经典成本最优规划,主流方法使用图神经网络(GNNs)。在这项工作中,我们继续使用GNN进行在线规划器选择的研究方向。我们对所选GNN模型、图表示和节点特征以及预测任务的影响进行了彻底调查。进一步,我们提出将GNN获得的图表示作为极端梯度提升(XGBoost)模型的输入,从而产生更资源高效且准确的方法。我们展示了各种基于GNN的在线规划器选择方法的有效性,为在线规划器选择的研究开辟了新的令人兴奋的途径。

英文摘要:

Online planner selection is the task of choosing a solver out of a predefined set for a given planning problem. As planning is computationally hard, the performance of solvers varies greatly on planning problems. Thus, the ability to predict their performance on a given problem is of great importance. While a variety of learning methods have been employed, for classical cost-optimal planning the prevailing approach uses Graph Neural Networks (GNNs). In this work, we continue the line of work on using GNNs for online planner selection. We perform a thorough investigation of the impact of the chosen GNN model, graph representation and node features, as well as prediction task. Going further, we propose using the graph representation obtained by a GNN as an input to the Extreme Gradient Boosting (XGBoost) model, resulting in a more resource-efficient yet accurate approach. We show the effectiveness of a variety of GNN-based online planner selection methods, opening up new exciting avenues for research on online planner selection.
